    I grab telemark's 4TBr1.tgz, so darn small and simple. Great stuff :up:. Couple questions:

    1) Will this image work for Premiere?
    2) How hard is it to create similar images for different size of hard drive?

    If telemark is willing, I would love to help creating a generic script and binaries to do a clean wipe of any TiVo of any size -- "The Ultimate TiVo Wipe" :D

    Thanks

    In its current iteration it will not work on Premiere series. Roamio series create their own images for any size drive up to 3TB.
    A question just popped into my mind since I am not sure about the details on how the Roamio finalizes the image upon first boot. Will there be a problem since the new software for the Roamio has been rewritten with a new interface from the version the community image was developed on.

    The installer could be described as a binary image writer and is limited by the image compatibility. The image used is currently Roamio model and version agnostic.

    Some of the concepts could be applied to Premiere and some effort is underway to apply that. I need to finish a couple tools first before I have proof or disproof of concept.

    Regarding different sizes, it's straightforward to make other images for common sizes. 500, 1TB, 2TB, 3TB. Compared to the Roamio's default partition layout, I chose more efficient layouts that reclaim a bit of un-utilized space. It's also possible to make a non-image based formatter for arbitrary but compatible sizes ( < 4TB for now ) but is more effort to code.

    The real advantage to using something like that over the default is the ability to alter / make custom allocations. This is also why I originally called this the community (public) edition because I thought of making a developer edition as well, with more Swap and /var to store software (but with reduced recording time).

    Could be caused by a couple explanations.

    Are you using a USB adapter?
    Did you hookup two Tivo drives by chance?

    Could you post back the output from these commands:
    > hdparm -N /dev/sdb
    > dmesg | grep sd
    > lsusb

    P55-UD6:/$ sudo hdparm -N /dev/sdb

    /dev/sdb:
    max sectors = 7814028911/7814037168, HPA is enabled

    Thanks

    That's not an acceptable setting. Wherever the drive came from, something set it. It needs to be permanently (which means across reboots) disabled.

    Background reading:
    http://en.wikipedia.org/wiki/Host_protected_area

    > hdparm -N p7814037168 /dev/sdX

    PS. The rest is Ok, you can delete it if you want some privacy.

    When you ask if I'm using a USB adapter - I hooked up the wd drive to direct sata cable but I do have an add on Anker USB 3.0 PCI-E card in my pc.

    Thanks again

    Ya, I asked that ambiguously.

    SATA works consistently.
    New USB-to-SATA adapters are suppose to work, but is not 100%.
    Old USB-to-SATA adapters are unlikely to work.

    I didn't notice your line of code above - per your suggested wiki reading I downloaded UBCD v531 - ran HDAT2 - removed HPA - set to full capacity and from that point everything ran great - within 45 mins I had 637 HD hours of recording available and was recording my first movie. P.S. didn't have to fuss with the cablecard settigs.

    Thanks telemark for all that you contribute to the fourm.

    On my Mac with a SATA to USB adapter, I can run jmfs (MfsLs and MfsLayout), and it recognizes the whole thing. I even tweaked MfsLs.java a bit to make it list files of arbitrary depth instead of the default depth of 1. With fuse-ext2 installed, I can also mount partition 4, 7, 9 and 14, see the kernel, logs and SQLite databases.

    However, I have not done any cloning and expansion yet. I am planning to do a 320GB to 500GB clone, followed by expansion with jmfs. I know it's not appropriate for this thread, because these are two Premieres, not Roamio.

    In any case, I think Mac should work fine.

    The only difference I've noticed on Mac is one of the block devices ( /dev/rdisk, /dev/disk ) would only support the device's native block size, which is different than Linux which would emulate multiple sizes.

    Is it just me or is the link no longer valid?

    "Sorry, we weren't able to locate that URL. Please double check your link details and try again. Or check back later."

    It's not just you. The two links appear not functional at this time.

    tiny.cc is down... It's not allowing new entries and others links appear non-operational as well.
    It's consistent with their internal database being offline.

    It's easiest to wait it out, and if they don't bring it back by tomorrow, I can migrate to another service.

    I can / have added an alternate link for the basic installer which bypasses tiny.cc, for those who can't wait, but it's only usable for those who can use tar/gzip on their own.

    Checking this morning and they're magically back now.
    I haven't changed anything so it was an outage.

    Sorry, my mistake. Firewall issue on my end.

    I haven't made any changes since Dropbox forced HTTPS, on 7/27/2014.

    That forces a 301, 302, before a 200, but it works in the end so I wanted to minimize changes until I could do a rewrite and comprehensive testing.

    I just did a run through and didn't see anything off. I'm not sure what you're experiencing from your description. Maybe post the last few message lines and what OS you're running and I can tell what actually is broken.
